Cannot start EMC with axis on a 10.04/2.4 system

hello,

I have persisting problems to use EMC 2.4.4 (Ub 10.04) with axis.
Other GUIs work perfect, including mocca, as well as the stepconf wizzard.

EMC with axis crashes with seg fault, whatever config I use. Could be old proven configs (yes removed NML...) or new created by stepconf. The same configs work with tkemc, mini, mocca (not touchy).

when I start emc -d I see this:
dmesg tells:
Anybody has a hint how to proceed ? what to check ?

thanks for help, Gerd

I noticed there were no replies to this post. Has anyone figured out Gerd's problem? I have the same issue with two desktops and a laptop at home using either the Live CD or full install, but the same Live CD works fine on Dell desktops and laptops at work.

Thanks,
Randy

i'm taking a stab at this , as i have had something similar , use apt-get and update or reinstall using package manager LibXext.so.6.4.0

CNCBasher,
Thanks, that didn't help. I rerun it over and over and over. Any interface except axis works. Axis and axis based interfaces crash. I notice the segmentation fault randomly occurs in other libraries. Below is my last run attempt and below that is other segfaultt from previous runs.

Thanks,
Randy

this usualy happens when some librarys are updated and some dependancys are missed or lost , is this with a clean installation of the live cd , or have you updated from an older release at some stage , try update manager if you happen to have the update manager turned off .

the problem you are seeing is an interoperability between librarys or library versions , and possibly an old incompatabilty with a library recently installed
form any newly installed application , using an old library .

it may be a better solution if this persists , to backup your emc config , and do a clean install of the live cd

look in the package manager for any conflicts or multiple versions of the same library , this may point you to a solution

Get the same results from the Live CD. It functions normally on my computer at work. So, I don't think it is a library mismatch from an update.

The errors above are from my desktop computer I want to use to run the cnc table. Reinstalled on my laptop and did all the recommended updates and no longer get the segfault errors. Now it says there is a configuration error, but fails to give any clue as to what the configuration error is or which config file is having the issue.

Andy,
Will try the software OpenGL when I get home this evening.

Thanks for all the ideas,
Randy

Andy,
The software OpenGL drivers did it. Thanks.

Now if I can get it to run on my laptop. I'm thinking my problem is no printer port on it. Is there a way run the software with out any hardware? I want to use my laptop to develop and test the code before going out to the garage to run it.
